I just purchased a 3 valve manifold with solenoids for a project and I would like to decode the part number. As there is a 12 in there I am hoping it is 12 volts. There are 2 wires on each side of each valve. The thing that puzzles me is that if I blow into the P port while blocking the T port I get flow from cylinder ports. Is this normal when no pressure and no electricity is applied? Google is not helping me to find valve specs, the number is 4we6h52/ag12nda s043a-488 rexroth
Any body familiar with these things?

Rexroth hydraulics is in fact Bosch, aka Robert Bosch, thier usual m.o. is to run at 24v, the mount being 3 flat plate terminals at the solenoid cap.
I’m sure they do 12. But that would bo the mobile kit for excavators cranes
Etc,
I don’t know how your block is connected but it’s going to be ceetop standard or EU standard, you could be looking at a different block as there was a screw in plug supposed to be in there making it a 4/5 to 2 spool animal
